Abstract:
Wireless sensor networks are used in a wide range of applications, including environmental
monitoring, industrial automation, and healthcare. In order to effectively
gather and analyze data from these networks, it is crucial to accurately determine
the position of the sensors. Range-free localization algorithms and techniques are
often used for this purpose, as they are able to adapt to changing conditions and do
not require the use of fixed ranges or predetermined reference points.
The DV-Hop algorithm is a popular choice for range-free localization, as it is
able to adapt to changing conditions and can be used in a variety of environments.
However, the DV-Hop algorithm has its limitations, as it can be prone to error and
may not be as accurate as other localization methods. In this study, we evaluated
the performance of the DV-Hop algorithm and its improved versions in order to
determine their accuracy and effectiveness in range-free localization.
Our results showed that the DV-Hop algorithm and its improved versions are
effective at determining the position of the sensors in a range-free wireless sensor
network, with the improved versions performing significantly better than the original
algorithm. However, there is still a significant level of error present, indicating that
further improvements could be made to increase the accuracy of the algorithm.
Overall, our study highlights the importance of range-free localization in wireless
sensor networks and the need for further research and development in this area in
order to improve the accuracy, efficiency, and adaptability of range-free localization
methods.
